EXPANSION PIPE-JOINT.

Specification of Letters Patent.

Application filed July 6,- 1910. Serial No. 570,545.

To all whom it'may concern: v Be it known that I, JAMES W. WYTON, a subject of the King of Great Britain, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Expansion Pipe-Joint, of which thefollowing is a full, clear, and exact description.

The invention is an improvement in expansion joints, and is primarily designed for use in the'length of steam pipe runn ng from the boiler to theengine of steamships,

heated fluid pressure pipes generally.

Figure 1 is a longitudinal central section v of an expansion pipe joint constructed in construction two accordance with my invention; and Fig. 2 is a cross-section of the same on the line 2-2 of Fig. 1. a

The expansion pipe joint embodies in its telescoping joint sections 5 and 6 respectively, each joint section shown to have an external flange 7 for, connecting the joint with the steam or other fluid pressure ,pipe. The joint section 6 is counterbored to slidably receive the telescoping portion of the joint section 5, and is further enlarged at its inner end to receive] a guide flange 8 arranged externally of the joint section 5. 6 is also shown to be provided with an. external flange 9, to the outer face of which is bolted a combined guide and stop rin 10, the inneredge of the ring affording aearing for the joint section 5 and lim1ting the separation of the two joint sections, the sliding movement otthe joint sections bein confined to the length of the counterbored end of the jointv section 6, minus the thickness of the guide flange 8. I

Snugly fitting within the joint sections 5 and 6, is a tubular closure or sealing member 11, made of copper 'or brass, or some metal having a relatively higher co-efii'cient The inner end of the joint sectionof expansion than the co-eflicient of expansion of the joint sections; The sealing member is preferably held in place, space or joint between the portions of the joint sections of the same diameter, by providing the member with an external flange 12 at one end, fitting within an annular recess formed in the outer face of the flange 7 of one of the j oint sections, shown to be the section 6. The sealing member internally tapers from a point near the center to its unflanged end, which is shown to be provided with a very thin or feather edge 13-,

whereby this portion'of the sealing member is very sensitive to the temperature of the pipe, and is easily expanded by the steam or other heated fluid pressure.

When the joint is applied to the steam orthe flange of the other fluid pressure pipe, latter, which bears against andis bolted to the flange 7 having the interfitting flange- 12 of the sealing member, bears against the flange 12 and eflectually prevents the dislocation of the sealing member when thejoint sections move within each other, under the expansion and contraction ofthe pipe. The'bearings between the two joint sections afforded by the inner telescoping portions and byv the guide flange 8 and ring or flange 10', act to effectively keep the joint sections in alinement, whereby there is no opportunity for one of the said sections binding within the other. When the steam or. other heated fluid pressure passes through the joint, the sealing member is expanded with-- in the pipe sections to a relatively greater extent than the expansion of the sections themselves, forming a fluid-tight joint in any position of the said sections within their limits of 'adjustment, thethin or feather edge of the sealing member bein pressed to the joint section within which 1t is placed,

bridging the. i

not only by reasonof the expansion of the member, but to a relatively greater extent than thethickerportion of the sealing memher, by the steam or fluid pressure.

Having thus described my invention, I claim as new and desire to secure Patent:

In an expansion pipe joint, a joint'section' having a double counterbore extending slidably fitting within the inner counterbored portion of the first and having an external guide flange bearing within t e outer ioo by Letters "from its inner end, a second joint section v counterbored portion of the first joint seoname to this s pecification'm the presence ofi tion, a guide ring secured' to the inner end two subscribing witnesses.

of the first joint section and bearing on the secondjoint section, and a tubular sealing W member fitting within the two sections of Witnesses:

the joint.
